　　In order to improve oxidation resistance of C/SiC composites fabricated by chemical vapor infiltration in a wide temperature range,dense SiBC matrix was introduced into C/SiC composites through in-situ reaction of B4C slurry and Si melt via a joint process of slurry infiltration and liquid silicon infiltration.Oxidation resistance of C/SiC-SiBC composites was studied compared with that of C/SiC composites.
